The vertical turret lathes and boring SC 11 SC 53 CC can perform following roughing and finishing operations: inner and outer turning, plane turning, annular groove turning. When equipped with special accessories, they can perform other operations too.

The models SC 11, SC 14(G), SC 17CC(G) have a single piece bed, movable cross rail, working supports in alternatives.

The lathe SC 11 is equipped with right hand vertical working head, and on special request it is also equipped with side working head.The lathe SC 14 CC (G) is equipped with right hand vertical working head and side working head.The lathe SC 17 CC (G) is equipped with two vertical working heads right-left and with side working head.

The models SC 22, SC 27, SC 33, SC 43 and SC 53 consists of a portal frame (bed, two columns, upper cover and stiffening beam), sliding cross rail, right hand vertical working head, left hand vertical working head, side working head.

In the standard versions, the lathes have the main spindle done with taper roller bearings.

On a special order, in (G) versions the lathes SC 14 CC(G), SC 17CC(G), SC 22(G), SC 27(G), SC 33(G), SC 43(G), SC 53(G), have the main spindle done with cross rail bearings which permit a heavier loading of the machines.

*For the vertical lathe SC 11 the head is delivered only as a special attachment.

Bed
The bed is a portal frame formed from two columns, linked by a table, an upper beam and a stiffening beam. These parts are assembled rigidly with screws and centering pins. The table, the upper beam, the columns are of high quality cast iron and heavily ribbed. Vertical guide ways are provided in front of the columns in order two ensure cross rail movement. On the upper part there are mounted the worm reducers for cross rail movement. There are 6 bed versions depending on their height (see technical features).
Plate and clamping supports
The plate is made of special cast iron and based a ribbed structure. Plate motion onto the bed is performed by means with cross roller bearings, tapered bearing, or hydrostatically. The plate is the actuated in turning mode through the gearbox (with heat treated cylindrical gears), by means of the secondary shaft and the electric motor with stepless adjustable speed. In milling mode the plate is actuated from an electric motor and slow feed box, using a duplex worm gearing an a hydraulic system for backlash compensation. The plate is hydraulic locked and released. The four clamping supports located on the plate, have a forget steel body and their jaws are made of cemented and hardened steel.
Movable cross rail The cross rail is one of the main parts of the lathe, with the role of guiding working supports and shifting the tool T in horizontal direction. Another role is of bearing the horizontal ball screw and supporting the horizontal feed reducer. The cross rail is the quality cast iron monoblock construction heavily ribbed, provided with guideways made of high alloy steel, heat treated and grinding that overtake the efforts without deformations. Cross rail moving on the bed is done rapidly and slowly by means of some trapezoidal screws driven by an electric motor by means of two worm reducer coupled mechanically. During part machining, the cross rail is locked in position on the upright beam guides by means of devices.
Working supports Vertical support “F” has the role for achieving milling turning, boring and drilling operations, guiding the railhead ram and achieving the horizontal movement (x-axis). It is made of a longitudinal slide of high - strength cast iron, heavily ribbed which moves along the cross rail.

Railhead ram

Railhead ram has a square section heaving dimension 250x250 / 250x300 mm.
The movements ram guiding in the vertical support is made by means of rolling elements and sliding plates in the direction of the main cutting force take-over.
The guiding together with rolling elements and sliding plates ensures precision high capacity and taking-over forces, as well as the lack of vibrations.
The railhead ram movement is done by a ball screw.
The railhead ram can be hydraulic blocked into the slide. Into the cross rail ram it is bearing milling spindle provided with an ISO cone.
